T-Mobile CEO John Legere, interviewed on the floor of the New York Stock Exchange in May

There was some speculation on Tuesday that T-Mobile CEO John Legere would use a special event today to share new numbers showing that the company’s new approach — no handset subsidies, no lock-in contracts — is winning it new customers.

That would be big news, because if the effort is succeeding, you can be pretty sure other carriers will end up offering similar deals. The convoluted system of selling $650 smartphones for a fraction of the cost, and making the money back by locking customers in to two-year contracts, is not particularly popular among mobile networks.

It is, for good reason, much more popular among handset makers, who don’t have to worry about convincing the public to pay full price for their expensive products.

But if new customers are flowing onto the T-Mobile network, we’ll have to wait until results are announced in August to find out about it. The company didn’t share the specifics today, although it hinted that things were looking good. From the WSJ’s Thomas Gryta:

T-Mobile didn’t provide national data on its turnaround effort, but said T-Mobile took market share from competitors during May in several major metropolitan areas.

“Our churn is lower than it has ever been,” Mr. Legere said. He said the customer additions weren’t driven by the April launch of the Apple Inc. (AAPL) iPhone, which made up 29% of its total smartphone sales in the second quarter. The company reports quarterly financial results next month.
